CVS Code Repositories

Locations

U.S. ATLAS Tier I Center maintains the mirror of ATLAS CVS repository at CVSROOT=/afs/usatlas.bnl.gov/software/cvs. This mirror is available for checkouts only. The import and commit operations should be performed with CERN ATLAS CVS repository that is accessible by the kserver or ssh methods only. For information on CVS commit history or hyperlinked code browsing please refer to the U.S. ATLAS Software Server and CERN Software Development web page

There is also the local U.S. ATLAS CVS repository for the personal work of U.S. ATLAS members and development projects that might in future go to the ATLAS repository. The personal modules are named with usatlas account usernames. The location is at CVSROOT=/afs/usatlas.bnl.gov/project/localcvs and the web browser is available for this repository.

When working with CERN CVS repository, gserver or ssh access methods can be used (see this page for details). Note that kserver access method is no longer available (since June 1, 2008).

For gserver access method the CERN Kerberos Version 5 ticket is needed. It can be obtained with kinit command:

setenv (or export) CVSROOT :gserver:isscvs.cern.ch:/local/reps/atlas
kinit <your CERN account>@CERN.CH

Also the executable /opt/usatlas/bin/cvs should be used (automatically included in PATH in US ATLAS group environment)

The advantage of ssh method is that it does not require kerberos tickets to access the CERN CVS repository. The setup is:

setenv (or export) CVS_RSH "ssh"
setenv (or export) CVSROOT ":ext:<your CERN account>@atlas-sw.cern.ch:/atlascvs"

In case of problems with the CERN CVS repository that require administrative rights to the latter, contact atlas-sw-cvsmanagers@cern.ch.

Note about CMT and CVS. In ATLAS release the packages have additional version directories which do not exist in the CVS repository. It is recommended to use cmt co operation for checkouts since it creates the correct directory hierarchy. See section 12 of CMT manual for details.

Tag Collection for ATLAS releases

The tags for ATLAS releases are collected by special tool Tag Collector. The Tag Collector provides the list of ATLAS releases and their tag content. The releases under construction are marked with a green or yellow "traffic light" that indicates an opened or locked status for the submission of new tags. The requests for version updates in locked releases should be sent to atlas-sw-tagapprove@cern.ch mailing list. For opened releases new versions are submitted through the Tag Collector web interface (with the condition that a developer must be in the managers or developers lists for the package). The new package versions appear in the next nightly build of the corresponding release.
